Overview
The THS4130IDGNR is a high-speed, low-noise, fully differential input/output amplifier produced by Texas Instruments. This device is part of the THS413x family, fabricated using Texas Instruments' state-of-the-art, high-voltage, complementary bipolar process. The THS4130IDGNR is designed to provide excellent common-mode noise rejection and low total harmonic distortion, making it suitable for high-voltage differential signal chains. It operates over a wide temperature range of –40°C to +85°C and supports single supply voltages from 5 V to 30 V.
